The car modification warranty stuff is discussed ad nauseam. The reality is that a significant chunk of performance vehicles have mods on them especially exhausts, intakes, and suspension stuff. Never heard of anyone having major warranty issues for this basic stuff. They have to prove the aftermarket part caused the issue to deny your warranty. If you have a cam phaser issue or whatever your exhaust won't be an issue.Now you tune an engine or slap a supercharger on an NA mustang yes your drivetrain repairs will more than likely be funded by you.
